' 2 Claims.

This invention relates to irrigating devices and more particularly to an improved sprinkler for sprinkling lawns, gardens and the like.

One object of the invention is to provide a lawn sprinkler so constructed that it may be readily moved from place to place without danger of injury to freshly planted runners of grass on the lawn.

Another object of theinvention is to provide a sprinkler having a low center of gravity and which, therefore, may not easily be overturned.

Another object of the invention is to provide a sprinkler wherein the sprinkler arm employed is curved and is formed with orifices, certain of which are so arranged that streams of water projecting therefrom will intersect, with the result that a fan-shaped spray of Water from the center of the sprinkler to the furthest edge of the wetted area will be produced, for assuring uniform irrigation of the entire area within the range of the sprinkler. Another object of the invention is to provide a sprinkler of this type employing a bearing which is sand-proofed for preventing entry of sand or other foreign matter.

Still another object of the invention is to provide a sprinkler wherein the T-head and sprinkler arm employed are mounted as a unit for assuring a rigid structure, said arm having a knurled portion engageable with the T-head for locking said T-head in place.

Another object of th invention is to provide a device of this character having plugs formed with jets for projecting streams of water for propelling the sprinkler head on the bearing, said plugs being removable from the ends of the arm for permitting easy cleaning of said arm. 1

Other objects of the invention not particularl mentioned hereinbefore will become apparent as the description proceeds.

In the accompanying drawings forming a part of this application:

Figure 1 is a perspective view of my improved sprinkler,

Figure 2 is an enlarged vertical sectional view on the line 2-2 of Figure 3,

Figure 3 is a side view, partly in section, of the bearing and T-head, and

Figure 4 is a horizontal sectional view on the line 4-4 of Figure 2.

Figure 5 is a fragmentary sectional view on an enlarged scale similar to Figure 2.

In the drawings, similar numerals of reference will be employed for designating like parts throughout the views.

Referring now more particularly to the drawlugs, and to Figure 1 in detail, the numeral 1 indicates in general the carriage of my improved sprinkler. The carriage 1 includes a supporting element 2 formed preferably from a strip of metal of suitable gauge. The element 2 includes a curved central portion which terminates in an upwardly curved runner 3. At its inner end, the element 2 is bent at an angle to define at attaching portion 4, and said element is connected to the center of a yoke 5 which mounts a roller 6. The roller is, of course, freely rotatable in the yoke and will cooperate with the runner 3 for permitting the carriage to be moved over a lawn or other surface with ease. It is desired to call particular attention to the fact that th roller 6 is relatively wide with respect to the height of the runner 3, with the result that the carriage will have a low center of gravity so that it may not easily be overturned.

Mounted on the central portion of the ele ment 2, near the yoke 5, is the body of my improved sprinkler, said body being indicated in general by the numeral 8. The body 8 includes an attaching shank 9 which is formed with lips l0, said lips overhanging the side edges of the central portion of the supporting element 2 and preventing rotation of the body. A nut H, screwed on a bolt projecting through the element, effectively retains the body on said element. The body 8 is provided with a coupling [2, of conventional design, and said coupling is, of course provided with the usual washer IS. The coupling, as will be seen, is presented toward the roller end or the carriag and is adapted for receiving the externally threaded end portion of a hose.

The body 8 also includes an upwardly presented internally threaded nipple I4 which is disposed in axial alignment with the shank 9, and screwed into said nipple is a sleeve which is indicated generally by the numeral I5. The sleeve l5 which forms a bearing for a rotatable member is best shown in Figures 2 and 3 of the drawings and is formed with an axial opening I! terminating at its lower end in a recess l8. The sleeve l5 also includes an externally threaded lower end portion [9 which is screwed into the nipple l4 and, near its upper end, said sleeve has a reduced portion 20 defining a shoulder 2|. Mounted in the recess I8 is a sealing washer 22.

Rotatably mounted in the axial opening I! of the sleeve I6 is a hollow spindle 24 which is flared at its lower end, as shown at 25, and includes an externally threaded upper end portion 26, said upper end portion extending past the upper limits of said sleeve. It will be noted that the flared portion 25 serves the three-fold function of retaining metal bearing washer 23 against a shoulder 233 formed in hollow spindle 24, of holding washer 22 in place in the recess [8, and of retaining the hollow spindle against upwardly displacement. Screwed on the externally threaded upper end portion 26 of the hollow spindle 24 is a T-head 21, said T-head having a shank 28 formed witha recess. 29 defining a shoulder 30. It willz be seen that the-recess 29 rotatably receives the reduced portion 29 of the stationary portion I6 and that the lower end of l the shank 26 abuts the shoulder 2!. The upper end of the portion 20 abuts the shoulder 36. It;

will now be understood that the T-head 21 is secured to spindle 24 and*rotatably connected Within the sleeve l6 and that the hollow spindle 24 efiectively prevents separation :of the T-head:

from said portion [6. The T-head 27 is formed with a horizontal opening 31 and, communicat-' ing between the open upper end of the spindle 24 and said opening 3|, is an'opening 32.

Rigidl-y mounted in the Thread 2'. and extending through the opening 3 1 therein is a sprinkler arm 33. The sprinkler arm includes bowed end portions 54' and 35which' are closed at their M outer ends by plugs-36 and 31; each of. which is formedwith a -jet 38! The 'ends of the arm are'turned downwardly approximately 45 from the horizontal and then are curvedupvvardly approximately 60, also from-the horizontal. The jets are so 'arranged that water projecting therefrom will impart rotative movement to the arm and T-head. Formed in the arm 33 at each side of the -T-head, aredisch'arge openings 39. As will be observed, three *discharge openings are formed in the arm at eachside of said T-head and said openingsarestaggered on'the circumference of-the arm; In this way 'aspray of water canfiow uniformlyifr'om the cente'r-of-the sprinkler to'the furthest edge 'of'th'e irrigated area. i

Water 'fi'owingfrom the jets "38 will, of course, provide, additional I irrigation? to that produced by water flowing fromthe openings 39'.

In manufacture, the T-head i's' preferably cast aboutthe arm 33 'withthe resultthat said T-hea d and arm will .be formed as a units. To assure that saidT-head will be rigidly'fixedton the arm"33,' andthatle'akage, willfbe prevented, said arm" is provided with aserratedportionrlil for receiving minute portions. of. molt'en metal-during casting of-said T-head.' The arm 33 islprovide'd withan opening 6i; within the T-"h"ead, which opening communicates with theflopening 32;

In use, a hose is,.oflcourse,'first. screwed into the-nipplelZ. The sprinklermay be moved over the surface to be watered .simply by pulling the hose in the desiredfdirection- As. pointed, out hereinbefore, the-centerptgravityof the car-. riage is: so low that dangersof overturning the device when; shifting ;it about will beeliminated. The roller 6 andwrunner 3swi 1l, of course, cooperate to permit/the devicefltotravel easily over the surface so that damagejkto grass will not occur.

Whemthe water.;is turned.:,on,.it.will .enter the body 8 and will flow upwardly through the hollow spindle I4 into the T-head and through the arm 33 at eachsidelofrsaid. T-T-head.: .From the arm 33, i streams.v ofziwater :will project through the openings 39 1' for effectively; irrigating; the 2 :area: surrounding thesprinkler; Water will, of course, also flow through the-.jetsx38 inthe plugs; 36 and 31:.for imparting rotativexlmovementto the arm andqT-head: about. the-bearing 15." As herein: before pointed'out,::however; the openings 39 are staggered fora-assuring imaximum distribution of. water. It .willrbe apparent frbmltheforegoing. description. thatzthe z'arrangement 'oi the open-,1 in'gs; sand the: curvature gOf ':.the-.-.endsi lofnthesarm 4 will cooperate for assuring uniform distribution of water.

Attention is particularly directed to the fact that the washer .22 in the recess 'l8.of the bearing 15 serves not only as an end thrust bearing for the hollow spindle I4 but, also, as means for taking up side thrust. This comtruction assures smooth operation and long wear.

It is believed that the construction and operation ofpmy improved-sprinkler will now be thoroughly understood.
